Baby Luv are great, we use them soley as our night nappys adn they're almost leak proof lol.
As for cloth ones with covers, I would just buy a couple of each type you see that looks like a bargain and then try them on your bubba. Every bubbas shape/ouput is different and you'll soon learn what you prefer. Alot of people like domes for instance but we prefer velcro as you get a better fit...although they (arguably) don't last as long.
Good luck, enjoy the MCN journey!
